There is a special form of a quadratic that is best for graphing the equation. We'll analyze it thoroughly here. Here y0 is the y coordinate of the vertex, x0 is the x coordinate of the vertex, and a is the amplitude, a measure of the thickness of the parabola.
Comments: Comments Off. According to the U.S. Geological Survey the average person uses between 80-100 gallons of water per day and estimates that 95% of the water we use, goes down the drain (1). So we waste 76-95 gallons per day. A shower, for example, uses between 2-5 gallons per minute.A dishwasher uses between 4-10 gallons of water for each load. A washing machine uses between 25-40 gallons of water every time we do a load of laundry.With just the use of basic water-using appliances, we use a lot of water. shower, for example, uses between 2-5 gallons per minute. A dishwasher uses between 4-10 gallons of water for each load. A washing machine uses between 25-40 gallons of water every time we do a load of laundry.
If you have a family of four and your hardness level is 10. Divide the 32,000 by your hardness (10), giving you 3,200 gallons of treated water. The average person uses about 75 gallons per day, so divide the 3,200 by 300 (75 gallons x 4 people). This gives you 11 days between regeneration.
